Why not just use CSS border-radius?

CSS border-radius works in browsers but not in email clients, PDFs, or print. This tool bakes the rounding into the image file itself.

Can I set different radii for each corner?

Yes. You can specify individual values for top-left, top-right, bottom-right, and bottom-left corners, just like the CSS shorthand.
